Finding the URL of an XMLHttpRequest object?

[johnnyb]

Hi,

Is it possible to find what URL was last used to make a request with an XMLHttpRequest object? I've been looking in documentation but can't seem to find a place where it says if this is possible.

Thanks,

John

I see that there is a property called channel in the XHR object in FireFox. Unfortunately I did some tests and it gives a permission denied error when I try to actually read it.

uncaught exception: Permission denied to get property XMLHttpRequest.channel

Bummer.

Strange. It's something you would think you would be able to find out.

I guess I'll have to propogate it in an external variable, unless there's a way to add properties to built-in objects.

Actually, you can add properties to built-in objects:

I'll have to make it work in IE6, but that's a start
